AUTOMOBILE-HEADLIGHT.

Specification of Lett ers Patent.

Patented. Dec. 27,1921.

Application filed August 9, 1920 Serial No. 402,157.

To all whom it may concern;

Be it known that I, HART F. LAN-DON, a

citizen of the United States, and. resident which can. be quickly andeasily applied to practically any type of vehicle head light.

An additional object is to provide an article of this nature which canbe struck or stamped from sheet metal and quickly bent into propershape.

Still another object of the invention is to provide a combined hood andlight retarding means which will cut off or reflect downwardly tllelight rays which are usually projected upwardly from head lights as atpres ent constructed. I

With these general objects in View, the

invention resides in the novel features of construction, combination andarrangement of parts which will be hereinafter more particularlydescribed and claimed.

In the accompanying drawings:

Figure 1 represents a vertical sectional view taken on the plane of theline 1-1 of Fig. 2.

Fig. 2 is a front elevational view of a head light having my improvedattachment applied thereto, and

Fig. 3 is a plan view of the attachment as it appears just after havingbeen struck from a suitable blank.

Referring more particularly to the drawings, it will be seen that myinvention is embodied in a head light of usual design including a.casing 1, a reflector 2 of the usual cup-shaped type having in its innerportion an incandescent lamp 3, a lens 4, and a lens retaining andassembling member 5. The casing 1 may be supported upon a suitablestandard 6, or any other preferred manner; likewise the current for thelamp 3 may be supplied as desired, for instance through the conductorwire 7.

The invention proper comprises a hood 8 and a light retardcr 9, theformer of which is disposed on the outside of the lens 4, whereas theretarder is on the inside thereof and within the cup-shaped reflector 2.Inasmuch as the rays of light which are projected through the lower halfof the lens 4 do not dazzle approachingpedestrians, or

the drivers of approaching vehicles, to any extent, this portion of ahead light is usually left unobscured, consequently in the presentinstance both the hood 8 and theretarder' 9 are disposed to shield theupper half of the lens 4 and to diffuse the light rays which normallyproject through such portion of the 'lens.

" The hood 8 in plan view,or beforebeing shaped, issubstantially in theform of a semi-circle as shown in Fig. 3,- but when bent in thenecessary manner, its intermedlate portlon is located somewhat above thecenter of the lens as indicated at 10 in Fig.

'2, whereas the end portions thereof extend below the center as at 11.The arcuate edge of the blank from which'the hood is formed is bentlaterally as at 12 to form. an attaching flange which, when the deviceis in place on the head light is clamped between the retaining member5and the lens 4 (see Fig.

1). Further and'more positive attachment of the end portions 11 isprocured as a result of the provision of attaching fingers 13,'the samebeing bent around the edge of the lensto embrace the inner and outerfaces thereof.

The light retarder 9 consistsof a semicircular frame 14 having aplurality, in the present instance three, light retarding plates 15which are disposed parallel and horizontally. In practice the frame 14and plates 15 are stamped from a semi-circular blank in such a mannerthat said plates are attached to the frame at their lower oppositecorner, such means of connection bein clearly indicated at 16 in Fig. 3.At eac opposite corner of the frame 14 is a lateral and diametricallyextending spacing and attaching leg 17 The hood 8 and the frame 14 arejoined in the center of their arcuate edges by a connecting1 strap 18,thus retaining the two parts of t e attachment together and ermittingready assembly thereof.

W en in use the hood 8 is applied as hereinbefore'set forth, whereas theconnecting strap 18 is bent into substantially U-shape to engage theedge of the lens 4, thus disposing the frame 14 and the parts carriedthereby on theinside of said lens. As indicated in Fig. l the frame ispositioned diagonally with respectto the vertical planeof the lens andhas, its lower end spaced therefrom by the legs 17. In view fthe factthat the material from which thisattachment is formed is of light gagesheet metal, these legs 17 as well as the attaching fingers 13 can bereadily bent about the edge of the lens, and consequently as a resultthe lower edge of the frame 14 can be spaced different distances awayfrom. the vertical plane extending through its upper edge. The retarderplates are bent inwardly in parallelism and as shown they preferablydefine an acute angle as with said frame so that although they retarddirect rays from the light 3, downwardly deflected rays from the upperportion of' the reflector 2 may pass therebetween.

From the foregoing description taken in connection with the accompanyingdrawings, it'will be seen that I have devised a very simply vconstructed light diffusing means which can be inexpensively formed oflight gage sheet metal and quickly and easily applied to standard typesof head lights. However,' should it be necessary, various changes may bemade in the form and proportions of the different parts, of theattachment to accommodate it for use in connection with unusual ty es ofhead lights, without departing from t e principles of the invention orsacrificing any of the advan tages Some of the rays which are projectedforwardly from the lamp or from the-reflector near its center will passunder or between the Wisconsin.

plates 15 either in a horizontal direction r inclined slightly upwardly.These for the most part will be deflected by the hood 8.

I claim:

1. The combination of a'headlight attachment comprising a one-piecehood, and light retarder bent to be disposed on opposite sides of aheadlight lens, the light retarder including a frame and a plurality oflight reflecting plates extending transversely across the frame inforwardly and downwardly disposed planes.

2. The combination of a headlight attachment comprising a one-piece hoodand light retarder bent to be disposed onopposite sides of a headlightlens, the light retarder including a downwardly and rearwardly exetending frame and a plurality of light reflecting plates extendingtransversely across the frame in forwardly and downwardly inclinedplanes, each plate being in rear of and below the preceding plate, andmeans for adjustably connecting the lower end of said frame to the sideedges of the lens to vary the angles of said plates.

3. In combination, aheadlight including a lens, a hood projectingforwardly from the upper portion of the headlight outside of the lens, alight reflecting member disposed within the headlight casing on theinside of said lens and extending downwardly and rearwardly from theupper edge thereof, and a connecting strip joining the hood andlightreflecting member and bent over the edge of the lens to aid in attachingthe same thereto.

In testimony that I claim the foregoing l have hereunto set my hand atMilwaukee in the county of, Milwaukee and State of HART r. aNnoN.
